DIMITRIOS PANTAZI, OF NEW YORK, N. Y.

SPRING-MOTOR.

Application led November 26, 1915, Serial No. 33,473.

To all whom t may concern: Be it known that I, Dnirrmos PANTAZI, asubject of the King of Greece, 'and a resident of New York, in thecounty of New York and State of New York, havev invented certain new anduseful Improvements in Spring-Motors, of which the following is aspecification. This invention relates to improvements in spring motorsand particularly of the type adapted to be used in connection with fansand other contrivances requiring a small amount of power to operate.

The principal object of the invention is to provide a motor which willrun for a greater length of time than is ordinary in constructions ofthis kind, the same occupying a relatively limited space in the base ofthe mechanism.

A second object is to provide means whereby the several springs may bewound simultaneously and with far less exertion than by the crankingmethods usually employed.

These and other objects, which will become more fully manifest as thespecification proceeds, are attained by the novel construction andcombination of parts hereafter described and shown in the accompanyingdrawings forming a material part of the specification, and in whichFigure 1 is a partial side elevation and sectional View showing anembodiment of the device, the section being taken substantially on line1 1 of Fig. 2,' and Fig. 2 is an end elevation of the same, the casingbeing shown in section to better disclose the interior.

In the adaptation shown a base 10 may be supported by a number ofpedestals 11 having a wide foot 12, so that the apparatus may be securedupon any convenient surace.

Rising from the base are two pairs of brackets 14 in which are rotatablymounted shafts 15, at one end ofwhich and between the brackets aresecured worm wheels 16 in such manner as to drive the shafts 15 whenthey are caused to rotate.

Motion is conveyed to the worm wheels 16 by means of the worms 17 rigidon the shaft 18 supported by brackets 19 transversely of the shafts 15,the shaft having one end extending beyond the casing and squared, as at20, to receive the crank handle 21.

Mounted to rotate on the shafts 15 are two drums 25 in which arecontained flat spiral coil springs 26, one end, as 27, beingl securedWithin the drum while the other end 28 is fastened upon the periphery ofa sleeve 29, the same being rigidly secured to the shaft 15, so thatwhen the shaft is rotated the spring will be wound. In lorder to conveymotion from the oppositely disposed drums a number ,of pins 30 are used,the same passing through a spur gear 31, loosely mounted upon the shaft15.

It will be understood that each pair of drums are similarly mounted andhave between them duplicate gears 31, both of which are adapted to meshwith the pinion 32 carried on the short shaft 33, supported by theframes 34 and 35, which are secured to the base as indicated.

The upper end of the frame side 35 extends vertically its entire lengthwhile the frame side 34 is bent, `as at 36, and then turned up to meetthe connecting bar 37 at the top.

Engaged with the pinion 32 is a train of gears leading to the pinion 40secured upon the shaft 4l, the extending end of which has rigidlymounted upon it the fan blades 42 as shown, the shaft revolving in lballbearings carried in the frame sides v35 and 36.

In the sides of the gear 40 are formed a number of openings 43 andadapted to engage with these openings are pins 44, carried by the detent45, which is provided with a hub 46, slidable on the shaft 47 andconstantly forced toward the gear by reason of the spiral push spring48.

All the foregoing mechanism is contained Within a metallic casing 5()secured to the base at its bottom and arranged to neatly cover over allof the described mechanism, except the handle 21, the fan head and thereleasing mechanism shown at the top of the casing.

This mechanism consists of a handle 52, the same being pivoted insuitable brackets 53 and provided with an angular lug 54 adapted to makecontact against the shift ing detent 45 opposing the spring when in l avertical position and capable of being turned, as indicated by the arrowin Fig.' 2, whereupon the pins 44 will engage with the gear and preventfurther motion of the clock train.

In operation the crank 21 is turned whereby the springs are tensioned,and the starti ing lever 52 moved either up or down, so as lto use thefan, or to have it remain quiet.

4two or more pairs of spring drunis, said druins being arranged in thesaine horizontal plane one in advance of the other, shafts upon whicheach pair of drums is rotatably mounted,`worrn wheels upon each of Saidshafts, ooil springs engaged interiorly of said drums atone end thereofand with said sliaftsat the other7 a shaft centrally between each groupof spring drums, gears combined with said drums (zo-acting to drive theseeond mentioned shaft, a train of gears driven by said second shaft, ashaft rotatably lmounted transversely of said drum and gea shafts, wormson the last named shaft meshing with said worm wheels, Ineansl forinanually rotating the last named shaft, and means for positivelyholding or releasing said gear train;

In testimony whereof I have signed iny naine to this Specification.
